The more I see and read, the more I think you really need to raise your prices... considerably. $9.99 for a 16" pizza is already a huge discount (unless the pizza comes from Domino's). If your pizza is any good--and those pics make me think it probably is--you're already giving people at least a few bucks off of every single pizza they buy. With that kind of pricing, you're just giving away money, and you're also telling everyone that your pizza is cheap. If you sell 100 pizzas a day with that kind of pricing, you're giving away $300. Every day. That's $9,000 every month and $108,000 a year. Just giving it away.
You can't stay in business if you just give away $100,000 a year. Many independents barely make that much in gross sales every year (which is a whole other conversation).
My guess is that you're not selling anywhere near 100 pizzas a day. You should be.
I went to a nearby pizza joint with my folks a year or so ago. Even though I used to deliver pizza in the same area this pizza joint serves, I didn't know much about Grandstand Pizza. In fact, I really didn't even want to go there. My impression, especially after seeing the menu (and the low prices), was that they served cheap pizza. If I was a regular pizza consumer, I wouldn't have ever ordered from them. So imagine my surprise when it turned out that their pizza is actually pretty good. It could use some work, but it was considerably better than I ever would have imagined.
I'm guessing a lot of people see Pizza Amore the same way I saw Grandstand Pizza. You have to figure out how to make them see it in a different way.
I suspect that starts with raising the prices enough to allow you to stay in business. If you raise your prices, most of your customers will understand, because your prices are ridiculously low. And the new customers you will have gained just by raising the prices won't even know you raised the prices, because right now they don't even know you exist. They don't know you exist because they don't care that you exist. They don't care that you exist because they've probably seen your prices and dismissed you as just another vendor of cheap, crappy pizza.
With higher regular prices, you can still offer really good deals. If your Mondays, Tuesdays, and Wednesdays are significantly slower than every other day, you can offer a really kick-ass Monday special, Tuesday Special, and/or a Wednesday special.
For example: Monday Night Special: $9.99 for a 14" 1-topping pizza.
Or $19.95 for two 14" 1-topping pizzas.
That seems like a couple pretty damn good deals, because they are good deals. But it's higher than your current regular price. I could come up with a whole bunch of these specials, and explain why they'd be better than $1 off or $2 off, especially considering your pizza is already at least $3 cheaper than it should be.
WEDNESDAY IS KIDS' NIGHT!!! Kids eat free (or something like that). You might have to offer a personal size for this. If you give away a 6" or 7" for every kid that brings their parents into your pizzeria, you make money. By giving away $1 or $2 worth of pizza, you end up selling at least another 14" pizza plus at least a couple drinks, on average. And even though it's similar to $1 off or $2 off, it's nothing like $1 off or $2 off.
With a kids' night, kids choose where the family eats. Marketing to kids is one of the best ways to stay in business. You have to think like a dope dealer. Give them a taste every now and then. If you do, most of those kids will grow up to become loyal paying customers. You make the rules, which are totally reasonable to the kids and the parents, and they accept the rules because the rules are favorable to them. In the process of creating lifetime customers (the kids), you've also made their parents loyal customers, who will remain loyal customers. (This is all assuming you have a dining room.)
Man, I could go on a long time.
